Overland Torque Tune (OTT) by Overland Tailor

Just spoke with him. He’s checking to see what/where the messages went. It may be helpful to drop him a note to put it back on top.

keep me posted, we’ll get you taken care of.

 

Thank you! I was just able to get ahold of JC Valenzuela. I’ll get it done one way or another

 

Anyone that has done this - knowing it's performance/shift/turbo focused, have you observed or measured any change in your MPG? Higher? Lower? Same as before?

 

It's the same as before or slightly better, depending on how I drive. I'm on 33s with 5.29 gears and steel front and back bumpers. Fuelly tells me I'm at 16.5 miles to a gallon, but I primarily drive highway miles until I get on base, and then it turns to city driving before I get to work.

 

Your bio says 4gen Tacoma. OTT suppose to be working on, or completed tune for 4th Gen. Contact OTT tuner in your location, and find out .

 

They've already released it. And I'm soliciting real world user reflections and observations. Thanks

 

It’s still early, but so far, we’ve tuned close to 100 4th Gens. Based on feedback from our retailers, most of those customers aren’t active on forums, and the Performance sub-section here gets only a fraction of the traffic that the main generational forums do. You might find a broader range of responses there.

That said, I want to set the right expectations regarding fuel economy. Given the nature of this calibration—where we’re significantly increasing airflow through the motor (+60 lb-ft of torque in areas)—it’s inevitable that more fuel will be used to do so safely. Because of that, we don’t make MPG improvement claims for this tune. If maximizing fuel economy is the primary goal, sticking with the stock tune will be the better approach.

However, in real-world driving, we’ve observed minimal impact on fuel economy—if driving habits remain consistent. Of course, if you’re getting heavily into the boost more often and running the truck up to redline (because, let’s be honest, it’s fun), you’ll likely see a decrease.

Hope that helps, and I’d be interested to hear from others on their experience as well!

 

gotta love an honest tuner!

 

100% agree

 

Super appreciative of this!

I'm a corner case I believe. I feel the HV has ample power for my needs, but I also feel like it's got an odd shift point challenge in the 37-47mph range and again in the 67-77mph range where the system feels like it might be fighting to decide whether to be ICE, to be battery, or to regen. So my interest in a potential tune would be purely if it might eliminate that due to the re-tune of the shift points and airflow expectations. But doing so I would want to hold, or beat factory observed MPG (for me about 20mpg in random mixed driving using Comfort or Normal mode on factory AVS and the General Grabbers.

Thus watching and injecting random questions now and then

 

this is very much a Toyota problem. The third gens suffered from it as well. I believe OTT has tuned that issue out in the past.

 

"Rev-Hang Reduction" - Update for 4th Gen Tacoma Manual Calibrations

We’re excited to announce an update for 4th Generation Tacoma manual transmission calibrations!

This update specifically targets "Rev-Hang", reducing the throttle hanging effect that many modern manual drivers find frustrating. The result is a more natural and responsive driving experience—better gear transitions, improved drivability, and that connected feel you expect from a manual.

This revision is now live and available at no additional cost to existing customers running our manual tune. If you’re already tuned and want the update, just reach out. And if you haven’t jumped in yet—now’s a great time.

Drive how you were meant to.

Just clicking through the OTT website today and the response times are quite long. Just want to make y'all aware.

 

Appreciate the update! I'll let our admin know.

 

I also recommend Jamey from central Georgia tuning. He set my second Gen up at a medium spicy level which he recommended for towing which I do a little of. My mpgs took a hit as well but I've only driven a little since I got the tune. On a highway trip to Orlando I was getting 17 -20 mpg on 33's before tune. After tune if was a flat 16.77 avg mpgs I'm going to drive a little longer before I decided if I want to go a little lower to pickup lost mpgs.

 

I got the OTT tune a couple of months ago. I went with mild/medium. I have been using 87 octane and have not tried 91. What difference would I notice with 91? 3.5 V6, 3rd gen.

 

You'll notice a slight improvement in output across the entire RPM range. But mostly the truck will just feel livlier and less burdened. The increase in ignition advance that'll occur as a result of using higher octane fuel will be noticeable, but not anything that will knock your socks off.

With the increase in advance, some folks do see a slight improvement in the economy when running premium fuel as well, though that's not a guarantee.
